Anyone here running the Dynatech supermaxx system with highflow cats and y-pipe? Any comments, good system or not worth the cost?

 

I've heard mixed reviews on it. Mostly about it fits poorly and does not line up too well. I'd get a set of The Other Guys or Arizona Speed and Marine headers.

 

do a search under o3gmc and supermaxx/headers/dynatech

to sum it up its a good quality system but the pass. side header on mine hits the frame (its sitting less than 1/8 away now, was about 1/4 after install) and this is the 2nd pass. side header they've sent me.

To be honest I would not buy the system again. If you do buy them, get them coated, my engine bay is hot now.

 

I posted some stuff on this system also, I had to cut and reweld the collectors to make it fit, I would not fit my truck w/o modifications.

 

Thanks for the info.
